I wasn't recommending it; I was just thinking of the old adage about 'men & their toys' and thinking that that might be a fairly harmless way to scratch that itch, except for the $500, of course.

Regarding PB => copper stains, so raise your chlorine levels carefully and slowly. Use many small doses rather than large ones. Run your filter 24/7 till you've reached high chlorine levels + high pH (7.8). That will reduce the chance of stains.
